Wastepaper Sludge Ash and Acid Tar as Activated Filler Aggregates for Stone Mastic Asphalt

Nowadays, the most common ways to dispose of acid tars and paper production waste are burial or incineration, but it is ecologically economically expedient use such in building materials. A new variant filler aggregate—wastepaper sludge ash (paper waste) a chemical activator for aggregates—acid tar (oil-refining industry proposed. Elemental mineralogical compositions wastepaper comparison with commodity limestone mineral powder established. Chemical activation was carried out wetting properties obtained materials were investigated by means primary neutralized tar. The physical mechanical stone mastic asphalt samples different aggregate variants studied. possible transformations using activated shown. possibility replacing traditional industrial has been proven, effectiveness activating aggregates confirmed. It established that as an does not require neutralization because asphalt, this case, demonstrates better compared neutralization. As result our research, application asphalt. And obtain improved characteristics, required activate 5 wt.%
